JAMES LOOHER, OF DECATUR, ILLINOIS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 349,805, dated September 28, 1886.

Application filed July 31, 1886. Serial No. 209,620.

To all whom it may concern:

Be it known that I, JAMns Locnnn, of the city of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Car-Couplers, of which the following is a specification.

My invention relates to car couplers in which the draw-bars are connected by links and pins; and it consists in certain details of construction and combinations of parts, as hereinafter set forth and claimed,whereby the operation of coupling maybe automatic.

In the drawings accompanying and forming a part of this specification, Figure 1 is a central vertical section of opposing draw bars constructed and coupled in accordance with my invention. Fig. 2 is a central vertical section of said draw-bars separate, and having the various parts properly adjusted preparatory to making a coupling automatically. Fig. 3 is a central vertical section of a drawbar. Fig. 4 is a horizontal section of the draw-bar shown in Fig. 3, 011 dotted line w; and Fig. 5 is a central vertical section of a draw-bar illustrating a modification of my invention.

a represents the draw-bar, having longitudinal recess a, link-guiding incline a, vertical aperture 9 9, slot (1, and groove 6.

b is a coupling-pin having enlarged head I) and conoidal point I).

c, c, c", and c, collectively, represent a triplever for the coupling-pin, 0 being a vertical bar extending through slot (1 into groove e, 0 being a horizontal upper extension of bar 0, 0 being a lower horizontal extension of bare, and 0 being an aperture in portion 0 of a size to freely admit pin 1). The pin and link are essentially the same as those commonly used in ordinary.hand-couplers, and the draw-bar may be attached to the car in any well-known manner. The trip-lever has a limited amount of free vertical motion in groove 6, and a limited amount of free pivotal motion in slot (2. Groove 6 lies to the rear of recess a, and when the bar 0 is in a vertical position in said groove there is nothing to oppose the insertion of the link to the extreme depth of the recess.

In preparing to make a coupling a trip-- (No model.)

trip-lever extending diagonally across the inner end of the recess of the draw-bar. "When the cars are moved together, the draw-bars come in contact one with the other, and the projecting end of thelink strikes the lower end of the trip-lever in the opposite draw-bar, car- 'rying said trip-lever into the position shown in Fig. 1, and causing the pin to fall and en gage the link. Then, as the draw-bars separate, through reaction or tension, the link is drawn from under termination c, and the pin and trip-lever fall, leaving all the parts in the positions shown in Fig. 1.

The uncoupling is effected by withdrawing a pin by hand, in the customary manner, and, if desired, a coupling may at any time be made by hand. As the trip-lever is thrown by the link, it carries the pin into a vertical position, and,with the assistance of the conoidal points 1), guides said pin through the link and into lower aperture, 9. r

In Fig. 2, the pin to the right is supported solely by friction, but in the modification set forth in Fig. 5 an upward extension of the trip-lever fits under the head of the pin, furnishing a positive support therefor. In both cases the link operates the .triplever, causing the pin to fall, and either form may be used with good results.

Having thus described my invention, I claim JAMES LOOHER.
